[PATCH 3/6] dt-bindings: phy-qcom-qmp: Update bindings for sdm845

[Manu Gautam]

Update compatible strings for USB3 PHYs on SDM845.
One is QMPv3 DisplayPort-USB combo PHY and other one
is USB UNI PHY which is single lane USB3 PHY without
DP capability.

[PATCH 5/6] dt-bindings: phy-qcom-usb2: Update bindings for sdm845

[Manu Gautam]

Update compatible strings for USB2 PHYs on sdm845.
There are two QUSB2 PHYs present on sdm845. Few PHY registers
programming is different for these PHYs related to electrical
parameters, otherwise both are same.

Register locations are different or tuning values are different? For the 
latter, is that something that could be DT properties?

There are only register values changes. Corresponding driver change:

Thanks for the patch.

"qcom,sdm845-1/2-qusb2-phy" gives an impression that it is different versions of SoC,
and not like two numbers of phy.
May be - "qcom,sdm845-qusb2-phy-1/2"

Vivek
